Well, it is just a second line of characters below English ones on the same standard keyboard, and a shourtcut for switching (not a separate key). Layout of letters phonetically is different from English ones (i.e. character identical to English A is placed on another key, and so on) - you may see it here (I believe it was designed in a way similar to QWERTY layout - to optimize motion of thumbs while typing in Russian). Not a big problem for blind typing, though - just a matter of habit.

Oh, thanks!Personally thought I completely failed the background this time. The sky is ok, but the ground is way too simple and schematic. (Should work on it several more days for good, but just grew too impatient to show the picture.)Glad you still like it!
